Researchers are continuously working on minimizing the cost occurring to obtain required quality and quantity of finished product within the international norms. Metal cutting is widely used for manufacturing of chips or debris .The authors studied and analyzed the various parameters that affects metal cutting .The paper concentrate towards the minimization of production cost further decreasing the chatter over workpiece and its subsequent effects .The different parameters were optimized by using six-sigma techniques and theirs effects on finished products were analyzed. The final desired surface finish of work piece through metal cutting were controlled by several factors which included spindle speed, frequency, vibration ,tool life etc. Chatter was caused by self induced vibration and the effect of high amplitude frequency and adversely affected at the resonance when the natural frequency and chip frequency were aligned It was observed that the chattering was highly effected by the spindle speed, at very low speed the chatter was almost negligible. In addition, the increase in spindle speed significantly decrease the chatter.
